Name: QuestDB
Rating: 5.0 (4 reviews)

QuestDB is the open-source time-series database for demanding workloads—from trading floors to mission control. It delivers ultra-low latency, high ingestion throughput, and a multi-tier storage engine. Native support for Parquet and SQL keeps your data portable, AI-ready—no vendor lock-in.

Hands down fastest database I've ever used. There is definitely a slight learning curve to getting it operational, and because of how new it is, it can be hard to find solutions online. That is a small price to pay for the fastest database ever. Not to mention that the community is incredibly strong, with remarkably fast response times. Cannot recommend enough.

We use QuestDB for our in-house analytics and audit log. This database powers Universal Link (Unilink) analytics.

Trading is all about Time-Series data. We chose QuestDB for its blazing fast ingestion and query performance for high-frequency market data and backtesting results. It handles millions of rows effortlessly where traditional SQL struggles.
